The Fellowes® AeraMax® Pro AM4 PC is the perfect wall mountable air purifier for large shared spaces; delivering 3-5 air changes per hour (ACH) in 60-110m² shared spaces. Thanks to the combined power of PureView™ and EnviroSmart™ technology, AeraMax Pro is the only air purifier that automatically responds to occupancy and air quality levels and then shows you when the air is clean. Proprietary and patented EnviroSmart™ technology uses an array of sensors to continuously monitor occupancy and room air quality and automatically adjusts to clean the air and the integrated PureView screen shows real time air quality data. The 4-stage H13 HEPA filtration system removes at least 99.95% of all airborne contaminants as small as 0.1 microns, including viruses and an antimicrobial HEPA treatment prevents bacteria growth on the filter and activated carbon filter reduces odours and VOCs. All Fellowes® AeraMax® Pro air purifiers were demonstrated through independent laboratory testing to be effective in reducing aerosolised airborne concentration of SARS-CoV-2 by over 99.99% through a single air pass test.
